When you make a muscle in your arm, you can see your biceps (say: BYE-seps). So take iTwixie’s Biggest GAINER Challenge! It’s easy!

Just tell your iTwixie BFFs 3 ways you used your biceps this week. Did you help put away groceries? You used your biceps! Did you carry books at school? You used your biceps! Did you bounce a basketball? You used your biceps! It’s that easy… so how did you use your biceps this week?

Here’s the thing: you cannot build really big bicep muscles until you are a teenager. Did you know that? But that doesn’t mean you cannot get stronger. So see how you can gain strength in your biceps this week!

Every girl who writes down 3 ways she used her biceps this week will earn a Biceps Achievement award

1:I do a daily work out routine containing Bicep workouts
2: climbing trees
3: holding babies (seriously I spent a lot of time holding babies on Sunday)
I didn’t know that you didn’t build up those muscles till you were a teenager. I guess you learn something new everyday
